Reaction Steps

5.4 ml of 28% methanolic solution of sodium methoxide and 2.3 g of 2-chloromethylpyridine hydrochloride were added, in turn, to a solution of 3.0 g 3-isobutyl-2-mercapto-4(3H-)quinazolinone in 50 ml of methanol, and the stirring was continued at room temperature for 15 hours. The reaction solution was poured into about 300 ml of water and extracted with chloroform. The extract was dried over sodium sulfate and the solvent was distilled off under reduced pressure. The residue was purified by silica column chromatography eluted with 10% ethyl acetate in chloroform. The fraction obtained from the eluent was further purified by crystallization from a mixture of ethyl acetate and diisopropylether to give 1.92 g of the title compound.
